If you like it, as you clearly do, keep it. It is a relatively rare car and will only get more rare in the future, and the great thing is that it is original. An American collector once told me that you only get one shot at originality, and that’s what you have got. That will come to enhance the value of your car as time goes by. The only thing to remember is that you need to maintain the car even though it’s sitting doing nothing, and drive it regularly. Do not just leave it sitting in the shed; that would just hasten its decline.

IF THE engineer is experienced, he will be used to listening for piston rattle and will hear it without driving the car. If you're not happy with the diagnosis, tell Holden of your concerns and take it to another Holden dealership for its opinion.
